Dear friend I'm new to Matlab and have zero coding experience I had this problem as i want to write new command

It keep written under that function loop, I tried to use 'end', but return error as Illegal use of reserved keyword "end"

How to exit the code folding for the function and start new command line?

code folding does not change the code itself, it only changes how the code is displayed. The error message tells you that you have written something wrong with your code, but the code folding cannot fix it, just show it, or hide it.

Try clicking on the small + symbol on the left-hand side of the editor to unfold the code (i.e. to see more of the code).

If you upload the code then we can tell you what is causing the error.

% --- Executes on button press in Apply.
function Apply_Callback(hObject, eventdata, handles)
% hObject    handle to Apply (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
mAs=(floor(mA))

Above it the code generated from GUI builder I try to write another code but it always end up being under Apply_Callback function.

How do I write code outside Apply_Callback function?

If you want a new function that is not to be considered as part of the Apply_Callback() function, then you need to use the "function" keyword:

function Apply_Callback(hObject, eventdata, handles)
% code for Apply_Callback()
% Now define your new function:
function mAs = MyNewFunction(ma)
mAs=(floor(mA));

Note that it is not possible in MATLAB to have a file that has both functions and "command line" (scripts). In a function file, everything has to be in a function.
